It is believed that the adaptive keyboard invented Artemy Lebedev, bringing out a keyboard “Optimus Maximus”. But in reality, this device was somewhat impractical. In the first place, of course, because of the inadequate price. OLED-displays on the keys look a bit unnatural. An interesting alternative is the keyboard under the name E-inkey. Concept E-inkey keyboard was designed by Maxim Mezentsev & Aleksander Suhih. The only difference works a device , that on a keys are placed not OLED-displays, and the small screen on electronic ink. Here, each key the conceptual wireless keyboard equipped with a display based on the technology of electronic paper. They look much more natural. This can significantly reduce the energy consumption , which means you can make a wireless keyboard E-inkey. For the “Optimus Maximus” it was not available. When working in different applications the user loads into the device profiles for key management, and all the functions are a little closer. This allows you to tailor the layout individually for each application. Do not we all remember keyboard shortcuts for even favorite programs.
